Equivalent IW102-1100 DOW Ultrafiltration Modules UF membrane modules

Introduction:

The replacement Dow IW102-1100 UF membrane module offers one of the largest membrane areas in the industry. It is an ideal choice for larger systems where it can contribute substantially to system savings by reducing fittings, frame materials, operating trains, valve stacks and overall system footprint. 

Replacement DOW IW102-1100 Ultrafiltration Modules can be used for a variety of treatment applications including surface water, seawater pretreatment, industrial wastewaters, and secondary effluent wastewater.

Replacement Dow IW102-1100 UF membrane module's feature:

• 102.5 m2 of filtration area to enable substantial reduction of capital costs for larger systems

• 0.03 µm pore size which enables removal of bacteria, viruses, and particulates; Up to 6 log 

• removal of bacteria, up to a 2.5 log removal of viruses, and <2.5 SDI filtrate quality PVDF fibers free of macro voids which offer excellent break resistance, chemical and fouling resistance; which allows for extended membrane life and consistent long term performance

• Outside-In flow configuration which allows for higher TSS feed waters, while maintaining reliable system performance and producing high quality filtrate

• Streamlined integrated PVC housing that eliminates non value added parts to make room for more fibers, while reducing fiber packing density at module extremities and improving removal of suspended solids to limit module fouling

• Integrated lifting handles improve ergonomics during installation and maintenance

• Potting design eliminates gaskets between filtrate and concentrate compartments reducing maintenance requirements and streamlines fiber repair in the unlikely event of fiber breakage
